Pete Buttigieg officially endorsed ex-rival Joe Biden for the Democratic presidential nomination ahead of a joint rally in Dallas on Monday night.

The ex-mayor of South Bend Ind., declared his enduring admiration and support for Biden, who just last week was his foe in the heated Democratic primary race.

“I’m looking for a leader, I’m looking for a president, who will draw out what’s best in each of us,” Buttigieg said. “We have found that leader in vice president, soon-to-be president, Joe Biden.”

Buttigieg, 38, described the former veep as “somebody of such extraordinary grace and kindness” with “ideas big enough to unite the american people.”

In return, Biden, 77, gushed that Buttigieg “reminds me of my son Beau.”

“It’s the highest compliment I could give to any man or woman,” Biden said.

Beau Biden, an Iraq War veteran who served as the attorney general of Delaware, died in May 2015 at 46 after battling brain cancer.

Both Buttigieg, who ended his White House race Sunday, and Amy Klobuchar, who withdrew on Monday, are backing Biden.

The developments come as Biden and the remaining Democratic field head into Super Tuesday, when 14 states go to the polls and 1,357 delegates are up for grabs.
